                                        <p>Pilot Ace was the fourth general purpose stored program electronic digital computer after <strong>Mark I</strong> on 21<sup>st</sup> June 1948, <strong>EDSAC</strong> on 6<sup>th</sup> May 1949 and <strong>SEAC</strong> on April 1950.</p>
                                        <p>A grand demonstration of Pilot ACE was held between 29<sup>th</sup> November and 1<sup>st</sup> December 1950. Two main programs were shown , one popular and one serious. The popular program took in a six digit decimal number and  gave it's highest factor. The serious program traced the paths of rays through a complex set of lenses.</p>
